The Trotters have been dragged back into the relegation dogfight after suffering back-to-back defeats in the Premier League.
With nine games of the season remaining, Gary Megson's men sit four points above the trapdoor to the Championship.
A lacklustre 3-1 defeat to Fulham on Saturday proved there is much work to be done before their top flight status is secure, with Cahill all too aware of the precarious situation the club find themselves in.
"It (the defeat) has brought us back involved but we've been in this situation before so the lads need to get together because next week is massively important," said the 23-year-old, referring to the trip to bottom club West Brom.
"We should be getting points and we haven't. We should have made it a lot easier for ourselves."
Cahill admits the weekend showing against Fulham was below par, with too many players allowing their standards to slip at a crucial stage of the campaign.
"We went into the game on the back of some good form at home so it was not a good performance to say the least," he added.
Tempo"We were lucky to come in 1-1 at half-time and I felt we couldn't go out in the second half and play as badly as we did, it was a very sloppy performance.
"It wasn't much of a spectacle, to say it was the Premier League it was a terrible game.
"The tempo was so slow it was almost like a training match and a few mistakes have cost us.
"Defensively as a team we were terrible. Our retention of the ball was terrible, a lot of things were terrible.
"We were all over the place, out of shape as a whole team, and you can't carry a couple of players.
"A lot of players had below-average games, that is their own fault. I'll analyse my own game and I know the lads will.
"The lads and everyone need to have a look at themselves."
